Although everyone is quoting the Supreme Court ruling but it only relates to the EA.
So if the organisers haven't invoked the EA presumably they can say who the walk is aimed at.
Unless and until somebody makes a complaint.
Not sure that (even though I support the idea) a women only walk would qualify as a proportionate means to meet a justifiable end. Unlike say toilets or women support services.
The problem is, this is all part of the minefield created by Stonewall etc., that has created the impression that identities etc., are as valid, real, as actual biological fact. And sadly many members of the public, not just entrenched TRAs think this is the norm.
And the fact that a charity is blithering on like this is no surprise.
So - and sorry if this has been already said - surely just a simple email to RSBP would alert them that what they have said doesn't match the Supreme court ruling.
It would be interesting to see what they say.
I suspect many people think it is just about toilers. Not about social events.
